Mal wieder was ins #Blog gepackt: zu #Ceph und den BLUESTORE_SLOW_OP_ERRORs, die da seit einem der letzten Updates herumschwirren. Spoiler: es ist weniger dramatisch, als ursprünglich angenommen, und man kann damit umgehen

Just updating a couple of my #Ceph nodes… it's been a long time on Debian 10, but I need to move on. Ansible no longer works with it.

Procedure so far is remove the old Ceph repositories (as they don't support anything beyond Debian 10) and lean on the fact that Debian 11 ships Ceph 14.

It's a slightly older release of Ceph 14, but it'll be enough… I can get the OS updated on all the nodes by doing them one-by-one… then when I get them all up to Debian 11… I should be able to jump to the next stable release of Ceph… then do another round of OS updates to move to Debian 12.

Ohhh boy.

Ok probably another week to go until I get these drives running

I should probably use that to figure out backups for this current pool.....

if the bulk storage poll in ceph works well enough I'll ship the current file server off to the parent's but for now I'll be able to use the LAN to do initial syncs

S3-compatible backup via Velero is one option, with MinIO, or Garage running in a container backed by ZFS (I am not building a remote ceph cluster )

Anyone have thoughts/suggestions on backup strategy here? Probably backing up 2-3TB of data total (lots of photos)

I'll end up with local snapshots, and remote backups, huge bonus if they can be recovered without needing a ceph cluster to restore to in the case of something catastrophic. #HomeLab #Ceph

Guess it's time for a new #introduction, post instance move.

Hi! I'm Crabbypup, or just 'crabby', though only in name most days.

I'm a Linux flavored computer toucher from Kitchener-Waterloo.

I tend to share stuff about the region, Open source software in general and #linux in specific.

I like to tinker in my #homelab, where I run #proxmox, #ceph, and a bunch of other #selfhosted services including #homeassistant.

I'm a rather inconsistent poster, but I'm glad to be here.

New blog post: https://blog.mei-home.net/posts/ceph-copy-latency/

I take a detailed look at the copy operation I recently did on my media collection, moving 1.7 TB from my old Ceph clusters to my Rook one.

Some musings about Ceph and HDDs as well as a satisfying amount of plots. Which are sadly not really readable. I definitely need a different blog theme which allows enlargement of figures.

There is no reason at all to entrust your company or personal data to ANY #Cloud service. If you are a company, build your own hardware infrastructure with #Ceph, #Proxmox, #Openstack or others. IT WILL SAVE YOU MONEY. If an individual back your data up at home on a NAS.
Use and support #OpenSource.
Ditch #Microsoft.
Now the US is bad, but no government or megacorporation can be trusted.

We have published a new newsletter about our current activity: https://blog.codeberg.org/letter-from-codeberg-looking-into-2025.html

* Meet us at #FOSDEM in Brussel and get stickers for you and your friends!
* Learn about our infrastructure improvements, networking and #Ceph storage.
* Read about other news from the past months.

I'm learning #Proxmox #cluster with #Ceph by virtualizing it on my Proxmox Mini PC. Total inception mode , but for learning purposes. The setup was relatively easy, and it worked very well.

- Manually migrate an LXC container from one node to another with only 10 seconds of downtime.

- Power off a node, and automatically migrate the LXC running on it to another node with one minute and 10 seconds of downtime.

I’m surprised by the last number. Any advice will be welcome.

I got my delivery of my new #kubernetes nodes (#minisforum #ms01). Now I'm waiting for ram and cables. Rather than decide between using the 10Gbit SFP+ ports and the USB-4 ports for the ring network (for #Ceph), I'm just going to set up both. That should give me 30Gbit between each node without using a switch.

Now I need to decide which OS I'll use. Stick with #RHEL 9, or change to #RockyLinux or #Fedora?

An exciting evening ahead of us: We are performing maintenance on our #Ceph storage system and will distribute data across the machines for the first time.

We expect no or little interruption of our services, but performance might degrade while the new nodes are backfilling.
